I need a gallery/art wordpress website

It’s hard when you don’t know what suits because I am not technically minded!!!

I would love to purchase a themeforest wordpress theme. I just don’t know what to purchase. Here is what I would need:-

1. CSS / valid XHTML , SEO compatible etc
2. To look more like a website than a blog
3. This is for my graphic design mainly which I want to sell, either by cart or order form so the customer can select details, fill in the form and it gets emailed to me
4. A blog component is ok but I don’t want it a major feature
5. I want a slider gallery on the 1st page for my art/pics/graphic design work
6. I want to be able to use google ads, other paid click ads in it
7. I use Facebook a lot, so the options to link Facebook and twitter and the likes, RSS feed etc
8. Options to upload my own business Logo at any size
9. Colours would have to be girly – pink, white, black, aqua options etc, and options to change the colours
10. Options to change layout or pages to different columns?
11. I would need a home page, services page, portfolio/gallery, contact me, blog, etc
12. I need a contact form
13. Need a simple ordering form… ie which product, what size print they want etc… the details they want on it, ie birth announcements or wedding announcements (photo card style) etc
14. Simple order form to buy some of my wall art
15. Shopping cart or pay pal or something for people to select and checkout????
16. I want a unique visitor counter to my page
17. Widgets to put in whatever I want??
18. Edit font, size and colour
19. No idea on slicing or anything… no idea on webdesign!!! I need specific instructions/help!!!
20. I would only need comments on the blog part or comments against the artwork maybe in my gallery
21. Ability to add as many pages I want to my website
22. Multilevel pages, ie click on my ‘services’ page and it will list a) ‘graphic design, my art work etc, b) amateur photography c) webservices, so when people click on these options, it opens a new page for that service
23. Compatibility with the most common browsers
24. Option to change background colours or background pic?
25. Sidebar widget options
26. Wordpress 2.9.2 Compatible? I think that’s the latest one?
